# Backward arrow rule is like a function call.
# Removes time and timezone info in the returned date
# Removes time info in the returned date
# The user in DL selects a date via the UI.
# These dates are persisted as midnight dateTimes in UTC.
# Meaning that 1st of July is stored as

# and 1 December
# "2022-11-30T23:00:00Z"^^xsd:dateTime
# So, the following rule adds 2 hours to the datetime, and then takes the date part of the UTC date time
# to come to the date that the DL user selected (in CE(S)T)
